encore payment systems aka prodigy payment systems?

Anyone know anything about this company?

A guy (sales rep) shows up at my door today rings the door bell and claimed he had an Appointment wit to get a credit card processing system. I told him um no you didn't. I did not authorize any such appointment. So he calls `the office' and I speak to some guy and tell him the same thing!

I check google and bunch of stuff on ripoff report and glass ceiling. Can't tell if they are and MLM even tho they claim you are `self employed"
